What is meant by the term "monomer"?

The term "monomer" refers to a molecule that can bond with other similar molecules to form a larger structure known as a polymer. In chemistry, monomers are the basic building blocks of polymers, and they can link together through chemical reactions, typically forming repeating units. This property is fundamental in various biological and synthetic contexts, as it allows for the creation of complex macromolecules from simpler units.

For instance, in the case of proteins, amino acids serve as monomers that can join to create polypeptides and eventually functional proteins. Similarly, in carbohydrates, simple sugars are monomers that combine to form starch or cellulose. Understanding monomers is essential for grasping how larger, complex structures are formed in chemical and biological processes.
